Trail running: which Active Rock sock to choose

On the road, every stride looks the same. On the trail, no two steps do. Roots, rocks, descents and loose gravel all ask something different of your feet.

Here is how to choose your Active Rock sock for the trail.

Which socks are best for trail running?

For trail running, choose a sock that holds your foot securely on uneven ground, has no toe seam to rub on long descents, manages sweat, and comes high enough to keep grit out of your shoe. An ankle-height sock usually suits the trail better than a low cut.

What the trail does to your feet

• Descents. Going downhill drives your foot forward into the toes, stride after stride.
• Uneven ground. Roots and rocks make the foot shift sideways inside the shoe.
• Grit and debris. Small stones and dust get into low shoes and rub at the collar.
• Long efforts. Trail runs usually last longer than road runs at the same distance.

Running Ankle: our pick for the trail

The Running Ankle adds coverage above the shoe collar, which helps keep grit out and protects the skin around the ankle from friction. It combines that with targeted cushioning, seamless construction and a breathable bamboo blend.

Running Low Cut: for smooth, dry trails

On well-groomed paths in summer, the Running Low Cut gives you the lightest feel. Its low profile leaves more skin exposed at the collar, so it is best when the trail is smooth and debris-free.

Compression for long days out

For long trail runs and races, our knee-high Compression socks support your legs during the effort and in recovery afterwards. More in which Active Rock running sock for which run.

Trail habits that save your feet

• Get the size right. A loose sock folds on descents. Check our size guide.
• Lace for the downhill. A secure heel lock stops your foot sliding forward.
• Empty your shoes as soon as you feel a stone. Small grit causes big blisters.
• Carry a spare pair on long runs and ultras.

Blisters are the most common reason a trail run goes wrong. Read the science of blister-free running.
